Bought these from a rock hounder in the desert

Hi friends! I recently took an 8000 miles road trip across the western US and got to visit a lot of rock shops and roadside sellers (the selling out of their yard folks always have the best stuff). I bought these from a guy near Zion, he didn't know what they were. Any ideas?

#1 dental battery from a Dino, hadrosaur, I think

 

#4 the most distal”toe” bone from a hadrosaur.  See photo for an example

I agree with item 1. Hadrosaur.

Anyone have ideas about the vert or skull? Some sort of oreodont maybe?

no oreodonts here.  I agree with the upper IDs and no3 might be a hadrosaur maxilla... the first photo seems to have some teeth visible.

Interesting, it doesn't look anything like the hadrosaur teeth I've found online, also it seems quite small in comparison to the others?
